Generic Java web application framework that allows the use of any script language via the standard Java Script Engine interface; Sling is RESTful by design and sits on top of a Java Content Repository, giving scripts full access to the JCR

A community open source Ajax-server based on the Mozilla browser (DOM + JavaScript engine). HTML, JavaScript, and CSS are native to Jaxer, as are XMLHttpRequests, JSON, DOM scripting, etc. It offers access to databases, files, and networking, as well as logging, process management, scalability, security, integration APIs, and extensibility. Not developed anymore by Aptana.

Extensions can be written in JavaScript, not just Java, especially servlets using the OSGiHTTP Service. Frontends can be developed with Eclipse RAP using the SWT and JFace APIs, or any other UI framework. Focus is on modularity (plug-ins), extensibility, scalability.

GromJS is a Server Side JavaScript (SSJS) interpreter which provides the ability to use an enhanced version of the JavaScript language on a web server with similar functionality to PHP, CGI, ASP, mod_perl or any other server side scripting solution.[4]

JavaScript is the server-side language used to develop services for the Opera Unite feature of the Opera browser. This is a server built into the browser. The JavaScript API includes local file access to a virtual sandboxed file-system and persistent storage via persistent global variables.

Prudence bills itself as "a comprehensive platform for REST services, such as web pages and RESTful APIs" and scales with automatic clustering. In addition to JavaScript, it supports Python, Ruby, PHP, Lua, Groovy, and Clojure. It differs from node.js in that it is multi-threaded, built for the JVM, and makes use of integrated caching.[8]

"SilkJS enables JavaScript as a scripting language in the server environment. You can think of SilkJS as a command shell, along the lines of Perl or PHP, except the language you write in is JavaScript."[9]

Bulletin Board System (BBS) software with integrated TCP/IP servers (written in C/C++ and enhanced via SSJS): Telnet, RLogin, SSH, HTTP[S], SMTP, POP3, as well as services written entirely in JavaScript: IMAP, NNTP, IRC, Finger, Gopher, etc. Includes some great classically-inspired "BBS doors" written entirely in JavaScript. Open Source and supported on Windows, Linux, and FreeBSD for little-endian architectures (e.g. X86 and ARM).

JavaScript and XML application development environment with bindings to PostgreSQL, Curl, libGD, Email and others. Most often used as an Apache module. Can also run a Whitebeam Shell for batch/background processes.

A Node.js fork called JXcore was created in January 2014, it gave people the choice between Google's V8 and Mozilla's SpiderMonkey JavaScript engines and it was possible to run Node.js applications on Android and iOS mobile devices. The development was stopped in March 2016 and focused on nodejs-mobile, a node-chakracore fork using Microsoft's ChakraCore JavaScript engine. Another fork, spidernode is inspired by node-chakracore but uses SpiderMonkey JavaScript engine instead.
